I can only tell you what I have seen, which is in most apartment buildings in my country, there are almost always some clothes washers and dryers on the ground floor or in the basement. I've read that in Poland, clothes dryers are one of the largest growing appliances in terms of sales, so it seems that many people there have discovered how convenient they can be, and how nice they leave one's clothes. Especially when one lives in a very small space, it seems terribly inconvenient to have clothes hanging around all the time.
I don't know, it doesn't take more than a day for my clothes to dry. I can't even afford some new shoes, I'm not going to buy some new electronics just to dry my clothes, slightly less slowly, I don't go through my clothes THAT quickly. It's just an extra expense, and now all of sudden I have more electronics I need to maintain.
My washing machine is good enough, no point in wasting money, when the sun can just do all the same work by itself. Washing clothes is tedious enough as is, I don't really feel like adding one extra step, among all the other expenses I might need to go through. Even when I used to live in a small flat, leaving the clothes around was never that big of a deal, I just had to adapt, and that was the end of it. I feel like I could be spending my money on something better than a dryer.
Even then, I feel like I would need two or three dryers, I doubt you can stuff those full of clothes, bed sheets, or whatever else, I would still need some storage space for my wet clothes and whatever else I have.
Honestly, I would rather buy a dishwasher instead. It would be far less useless than a dryer in my mind. And it would automate some really tedious busy work.
I would buy a dryer if I had the money for it though, I'm not really against it.
I sure as hell wouldn't complain, if I could just throw all my crap into the dryer for a couple of hours, and be done with it.
I would gladly have both a dish washer and a dryer, but overall, I feel like the dishwasher would get more use than a dryer. I doubt a dryer would use too much electricity, it's probably just a motor that makes some spinny stuff spin.
I'm not suggesting that people without clothes dryers rush out and buy them, but in a situation like Ross's, it makes sense to throw your damp clothes into a basket and seek one out instead of creating further moisture problems in the home. For all we know, there is a dryer within a short walk or drive from his mold-infested home. Additionally, your comments tell me that you are unfamiliar with a modern tumble dryer, which is fine, I am not insulting you, but perhaps it is hasty to characterize something as useless when it is evident you haven't researched its principles of operation or its functionality. For instance, the dryer that I'm familiar with can have a full load of clothes crisp, clean, and dry in under 45 minutes. So basically once one washer load is done, the next can be placed in the dryer and so on. Furthermore, I would think that if there are active mold spores in the air, they would find a ready home in damp clothing, such that you'd actually be wearing the toxins that could be making you sick. It's just a horrible idea in his situation.
